Abstract
A memory mapped I/O scheme treats each I/O buffer as a memory element which can be addressed, written into or read from. Each I/O buffer has its own memory address decoder which eliminates the need for special select/control lines for each buffer and enables the use of a single address/data bus. Thus redesign and reconfiguration of the I/O buffers is more easily accomplished because it does not require new select/control lines to be laid out when buffer locations are changed.
